    Background and Objectives: Thrombolysis of Isolated calf vein thrombosis (CVT) is not clearly studied. We investigated the thrombi in patients with deep vein thrombosis (DVT) from the initial time of diagnosis using ultrasonography (US). Methods: Of the 2,299 consecutive patients undergoing venous US between October 2010 and March 2015, we enrolled 198 patients with DVT who were monitored using US from the initial time of diagnosis (mean follow-up was 156±210 days). The patients were devided into three groups according to the segment of thrombi, ilio-femoral (group I), femoro-popliteal (group F) and localized calf (group C). Results: Thrombolysis occurred in 39 limbs in group C, 21 limbs in group I and 24 limbs in group F (p=0.034). In group C, reduction in thrombus size occurred 64.1% after over 30 days follow-up (p=0.029). Conclusion: In patients with CVT, long term follow-up with US is beneficial compared with proximal DVT.
